Research challenges the impact of growth mindset on long-term performance

Emerging evidence questions the effectiveness of growth mindset interventions as standalone solutions, highlighting the need for integrated approaches that include structured learning and behaviour change.

Growth mindset has become one of the most familiar ideas in schools and workplaces: the belief that ability can be developed through effort, strategy and practice. But a growing body of research suggests that the slogan has often outpaced the evidence. A 2023 meta-analysis by Macnamara and Burgoyne, covering 63 studies and nearly 100,000 students, found only a tiny effect on academic achievement, and that effect disappeared after adjusting for publication bias. A 2025 structured review by Gazmuri reached a similar conclusion, saying the evidence remains inconsistent and uneven in quality.

That matters because growth mindset was never just an academic phrase. It became a staple of leadership courses, classroom posters and corporate training, often presented as a simple fix for underperformance, fear of failure and resistance to change. Yet the research reviewed by the What Works Clearinghouse found no clear effect on college enrolment or progression, while a separate review by Yeager and colleagues found only small gains that varied widely by setting. The recurring pattern is that belief alone is not enough to shift outcomes in any durable way.

The weakness of the intervention, critics argue, is that it teaches people what to think without showing them what to do next. That is where self-leadership becomes relevant. The central idea is straightforward: a growth-oriented belief may help people interpret setbacks more constructively, but it still needs habits, feedback loops and disciplined practice to turn into performance. In other words, mindset can point the way, but it does not supply the method.

For organisations, the practical lesson is less about abandoning the concept than about treating it more carefully. Gazmuri’s review suggests that the field still needs stronger methods and better evidence before making confident claims about impact, and Tipton and colleagues have argued that meta-analyses in this area need more rigorous treatment of variation between studies. That makes broad promises risky, especially when a training programme is sold as a solution rather than as one piece of a wider development system.

So the real question is not whether people can improve; it is whether an organisation is giving them the tools to do so. The evidence so far suggests that growth mindset, on its own, is too thin to carry that burden. Where it may have value is as part of a broader approach that includes structured learning, honest feedback and concrete behaviour change.
